One thing to not forget, this interview was done when they only had one script written and we all know that they change things, they even said that, remenber Robin hood dark past, so from this i can make that they dont know half of this answers and they say most maybes, to avoid giving real answers and they can always say to fans that they never said yes and is not their problem if they thought maybe means yes. And most of these questions depends if this would be last season or not, for example wedding.
